1. Not flossing
Brushing your teeth twice a day is important, but many patients don't realize that flossing at least once a day is just as critical to achieving - and maintaining - a healthy smile. Flossing removes the cavity-causing bacteria left behind from food particles that get stuck between teeth.

2. Brushing too soon after eating
Consuming acidic foods and beverages, such as sports and energy drinks, citrus fruits, wine, and tomatoes, can erode tooth enamel - the glossy outer layer of the tooth. Brushing your teeth too soon after eating and drinking these items can cause more damage because you are essentially brushing the acid into the teeth, not getting rid of it. Instead, you should rinse your mouth with water after consuming acidic foods and beverages and wait at least 30 minutes before brushing your pearly whites!

3. Not replacing your toothbrush often enough
Not only are old toothbrushes ineffective, but they also harbor harmful bacteria that can cause infections. Toothbrushes should be changed every three to four months.

4. Excessively bleaching your teeth
Overzealous bleaching can cause your teeth to look unnaturally white and increase tooth sensitivity. Before using an at-home bleaching product, talk to your dentist.

5. Using a hard-bristled toothbrush
A hard-bristled toothbrush coupled with an aggressive brushing technique can cause irreversible damage to your gums. Use a soft toothbrush and gently brush your teeth at a 45-degree angle, in a circular motion. Using a back-and-forth, the sawing motion causes the gums to recede, and can expose the root of the tooth, making teeth extremely sensitive.

Keeping your brush at a 45 degree angle while brushing so that the bristles do not hurt your gums.
